I have two machines running the Nagios Daemon. One for all internal 
machines, one for all external machines.

Yes, it's rather long. Some Services are defined in 
services_nagios2.cfg, but most Services are defined in the Host 
configuration itself, example:

define service{
        use                             generic-service         ; Name 
of service template to use
        host_name                       vm.local
        service_description             Disk Space
        check_command                   check_nrpe_1arg!check_all_disks
        notification_interval		0
        }

define service{
        use                             generic-service         ; Name 
of service template to use
        host_name                       vm.local
        service_description             VirtualBox WinXP IE6
	check_command                   check_nrpe_1arg!check_vm_wxpie6
        notification_interval		0
	}

define service{
        use                             generic-service         ; Name 
of service template to use
        host_name                       vm.local
        service_description             VirtualBox WinXP IE7
	check_command                   check_nrpe_1arg!check_vm_wxpie7
        notification_interval		0
	}

define service{
        use                             generic-service         ; Name 
of service template to use
        host_name                       vm.local
        service_description             VirtualBox WinXP IE8
	check_command                   check_nrpe_1arg!check_vm_wxpie8
        notification_interval		0
	}

I didn't post them as I don't think it has anything to do with the problem.

Events working fine. Warnings, Critical, Recovery, Acknowledge 
everything works as expected. So, yes, it might be just a CGI-Problem.

I've purged the Nagios installation (apt-get purge nagios*) and checked 
that all config files we're deleted. The I reinstalled Nagios (localhost 
was shown correctly). Then I just copied the dx_nagios2.cfg and the 
vm_nagios2.cfg into "conf.d". Same problem as before.

Also I compared the "internal" config with the "external" config (again) 
but can't see any difference. Beside from the Host-Config and the 
htpasswd.users it is identical, according to "diff".

Anyway I was able to narrow it down to one single config file 
(dx_nagios2.conf) but I can't see any flaw in it. The funny thing is, if 
I rename the host from "dx.local" to "zdx.local" everything works fine 
as the Host is the last Host to show up in "Services".

Strange, but I think I can live with that.

Thanks for your help.

Bye.
